Hello. Clearly I have managed to louse up my configuration, but I am not sure how.
TL;DR
Hass.io (supervisor v140?), Raspberry PI3b, Home Assistant 0.83.1, zigbee2mqtt v0.2.0
sensors talking zigbee to mqtt to home assistant have nice “Friendly Names” but also have a set of “MQTT_Sensor” duplicated copies each.
I would like to remove the duplicates, ideally ending up with each sensor named something under my control.
Details
So I have a count of Xiaomi Aqara sensors talking zigbee to zigbee2mqtt talking to Home Assistant.
I have manually entered a “Friendly Name” for each sensor in zigbee2mqtt’s configuration.yaml, and sensors named for these appear in my history and I can attach groups to them, so that works nice.
But I also have a dozen “sensor.mqtt_sensor_$X” each with a friendly name of “MQTT Sensor”, showing as little red circles outside the groups in the image above. Ungrouped sensors show as red/blue circles with the friendly name - “router1”, “sense_door_1”, and so forth.
I suspect discovery and my manually entered values are fighting, but I am not sure how to fix things.
Back in 0.81, I only had one MQTT_sensor, so I set it to ‘hidden’ and carried on. But after updating to 0.83.1 and now I have a dozen or more so it may be time to fix things

I am using groups.yaml to group the sensors into little cards. No lovelace (yet).
thp1_group:

- sensor.sense_thp_1_linkquality
- sensor.sense_thp_1_temperature
- sensor.sense_thp_1_humidity

(I can grab the MQTT messages on zigbee2mqtt start if that is useful, I have resisted so far, to prevent wall-of-text syndrome)
Next steps
I have experimented with turning off “discovery” in configuration.yaml, but that seems to make things worse. I figure I should ask for help before I break things even more completely! 
Does anyone have any suggestions for where I should look or what I should try next?
- Should I try to delete my manually created sensors from the main configuration.yaml and look for a way to discriminate the Friendly Name: “MQTT Sensors” and rename them something useful?
- or some other approach entirely?
Thanks!
